all your welds are belong to me!
 

made a welder out of 11.1 V 2200mAh 20C battery and paperclips!

paper clips welded together - 2

working miatas in possession- 0

:giggle:

burn!

I welded these razorblades together with a 9-Volt battery and an old paperclip <G>:

Anyone doing a writeup on this DIY welding?

i wouldnt reccomend welding anything you dont want to crack.

I just used flux core to weld a ss vband to my cast turbine housing. I used half a 1lb spool of wire on it. Think it will hold?

yes, need more of this.

You don't even need a 9volt... I welded a rollcage with matches.

:bowrofl:

Umm. Metallurgically i would say no. Cast iron has high carbon percentages. Where SS has chromium/nickel and low carbon content. The fact that you used flux core will add more impurities in the weld making it more likely to fail vs using MIG/TIG/STICK. Keep in mind that this will recieve the more extreme heating/cooling cycles out of any part of your exhaust. What i would of done is used TIG using cast iron filler. But ive heard of crazier things sticking togethor so i could be wrong. Did you ping the weld? (hit it with a blunted hammer to relieve the stress caused by heating the cast iron) Probably not. I hope for the best :2cents:

I hit it with a hammer to remove and slag and weld that did not stick. So I guess, yes, I did "ping" the weld. I welded the entire perimeter and it is on there what appears to be very string. I hit the 1/2" flange on the vband section with a sledge and it didn't come flying off. Also the penetration appears to be good. With the amount of welded area I just don't see how it could fall off. I know others who have done the same before, albeit with regular wire and shielding gas, and theirs have put up with everything they can throw at it.

Oh shit. (gasp)

Literal LOL. :laugh:
